Definition : Computerized network devices designed to establish dedicated paths between end users (i.e., personal computers), providing communication channels between them. These devices are typically electronic units with circuits that work as switches; network switches are usually capable of inspecting data packets and may also store and subsequently forward information, offering better performance than a hub. By delivering each message only to the device for which it is intended, a network switch facilitates the use of multiple computers and/or other devices together in the same local area network; network switches may be specific for use in a particular network model and/or with equipment from a specific manufacturer.

Information on how to use Search
There are 2 types of basic queries: Terms and Phrases.
A Term is a single word search.
A Phrase would wrap a string of words in quotes and find matches on the extact string.
Boolean Operators You can combine basic queries with Boolean operators to form a more complex query. Boolean operators define the relationships between Terms or Phrases. Our search supports the following Boolean operators: AND, "+", OR, NOT and "-". Please note that Boolean operators must be all uppercase.
AND example search: default AND document
This is the default operator. It will be used if there is no Boolean operator between two terms. For example:
default document is the same as default AND document. In this case both terms need to exist within a listing to find a match on that listing.The + character is synonymous with using AND.
OR example search: default OR document
In this case just one of the terms needs to exist within a listing to find a match on that listing.
NOT example search: default NOT "document type"
The NOT operator excludes documents that contain the term (or phrase) after NOT. So a listing match would have to include the word default but not the phrase "document type". The - character is synonymous with using NOT.
Wildcard/Prefix queries You can perform "wildcard" or "prefix" queries using the '*' operator. Whereas all of the previous search found exact matches on the whole term or phrase, a wildcard search will find partial matches.
example search: ehr*
This query will match all documents containing words beginning with the prefix 'ehr' like the word Ehrlichia.
